Solve and graph the absolute value inequality: |2x + 4| > 14 A.)number line with open circles on −9 and 5, shading going in the opposite directions. B.) number line with open circles on −9 and 5, shading in between. C.) number line with closed circles on −9 and 5, shading going in the opposite directions. D.) a number line with open circles on −5 and 5, shading going in the opposite directions.
|2x + 4| > 14 2x + 4 > 14 or 2x + 4 < -14 2x > 14-4 or 2x < -14-4 2x > 10 or 2x < -18 x > 10/2 or x < -18/2 x > 5 or x < -9 So to graph this we step 1) Draw a number line step 2) plot open circles at 5 and 9 step 3) shade to the right of 5 step 4) shade to the left of -9 Note: every region but the middle region is shaded in Wolfram Alpha has the graph (at the very bottom) http://www.wolframalpha.com/input/?i=%7C2x%20%2B%204%7C%20%3E%2014&t=crmtb01&f=rc
